UNITED STATES JOHN HEINKEL, OF ST. LOUIS, MISSOURI.

rno'on DRAIN.

Application filed July 29, 1921. Serial No. 488,296.

To all whom it may concern:

Be it known that 1, JOHN I-IEINKEL, a. citizen of the United States,residing at St. Louis, in the county of St. Louis and State 5 ofMissouri, have invented certain new and useful Improvements in FloorDrains, 0 which the following is a specification;

My invention has reference to floor drains, of that class which are tobe found in the basement floors of buildings. Many of these drains arefitted with plates which are insecurely held in place, and which areliable to rock or slip upon being stepped upon. When thus used inschools and other places where children congregate, there is danger ofinjury to such children, resulting from the accidental movement of thedrain-plate.

There is also danger of the plate being re-.

moved by the smaller children, leaving the opening to the drain exposed,with the risk incidental thereto.

The chief purpose of the present invention is to provide a means bywhich the drainplate can be held securely in place, Without anypossibility of the same moving so as to cause injury to a person whosteps thereon. The manner in which this is accomplished will more fullyappear from the following specification, taken in connection with theaccompanying drawings, in which:

Fig. l is a plan view of the invention.

Fig. 2 is a cross-section of the plate shown in Fig. 1, on the'brokenline 6- -6 thereof.

As shown in the figures the drain plate is formed of two sections, 17and 18, having overlapping edges 19 and 20, and projections f When it isdesired 21 at'the sides, adapted to enter recesses in the rim of thebowl. At a central point the plate sections are held together by a screw23, passing through the flanges 19 and 20, and preventing removal of theplate.

to remove the same the screw 23 is removed and the plate sections raisedalong the line of the joint, whereupon the tongues '21 can be slippedout of the recesses in the rim. Even with the screw 23 removed there islittle danger of the sections of the plate sliding, as the parts areinterlocked at the joint.

it has been customary to ship the drains and plates separately, as aresult of which the plates have become mis-laid or lost. \Vith theconstruction herein set forth, it is possible to have the partsassembled for transportation and storage, eliminating danger of loss ofthe plates.

WVha-t I claim, and desire to secure by Letters Patent, is: I

A device of the class described, comprising a drain inlet, provided witha rim having recesses in its opposite sides; a divided plate havingoverlapping inner edges, and provided on its opposite outside edges withtongues capable of entering said recesses, and locking said plate fromrelease when the parts thereof are in an extended position; and aconnecting means for holding said inner edges normally in engagement,with the parts of said drain-plate 1n extended position.

In testimony whereof I afiix my signature.

JOHN HEINKEL.
